Look for the Label: Window Performance Can Be Measured
Will new windows really save you money by keeping your house warmer in winter and cooler in summer? Yes, and you can even measure a window’s performance.
An independent national organization called the National Fenestration Rating Council (NFRC) conducts laboratory tests on windows to measure and rate several factors that affect thermal performance. Look for the NRFC label on any window you buy for your home or commercial property. Here is what you will discover:
- U-Factor: this shows how well a product prevents heat from escaping.
- Solar Heat Gain Coefficient: measures how well a product blocks heat caused by sunlight.
- Visible Transmittance: measures how much light comes through a product.
